WASHINGTON (AP) — In-house newsletters from the clandestine National Security Agency have been released by an online news site — part of the mountain of documents leaked by former NSA contractor Edward Snowden.

An online news site, The Intercept, whose founding editors were the first to publish documents leaked by Snowden, released the newsletters Monday. The first batch of nine years’ worth of the newsletters offers a behind-the-scenes glimpse into the NSA’s work.
